WINDOW-HOLDER.

Specification of Letters Patent.

Patented Apr. 21, 1914.

Application filed November 18, 1913. Serial No. 801,633.

To all whom t may conce/m.'

Be it known that I, ARTHUR A. MILLER, a citizen of the Unitedv States,residing at Kapowsin, in the county of Pierce and State of Washington,have invented certain new and useful Improvements in VVindow-Holders;and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to window holders and has for its object toprovide an improved device of this character which is designed formounting` upon one of the side rails of a window-sash and constructedfor engagement with the adjacent portion of the window frame so as tolock the sash when the latter is in an elevated position.

A further object is to provide a yieldable housing for the window frameengaging member whereby the latter will not become jammed, displaced orbroken.

With these and other objects the present invention consists in thecombination and arrangement of parts as will be hereinafter more fullydescribed and shown in the drawings and particularly pointed out in theappended claims.

Like characters of reference designate corresponding parts in all of thefigures of the drawings.

1n the `accompanying drawings :#Figure l is a fragmentary view of awindow frame and sash showing my improved invention attached thereto;Fig. 2 is a vertical longitudinal section taken on the line 2-2 of Fig.4, showing the frame engaging member in projected position; Fig. 3 is asimilar view showing the frame engaging member in retracted position.Fig. 4i is a horizontal sectional view taken on the line Jr-1 of Fig. 2.Fig. 5 is a similar view taken on the line 5 5 of Fig. 3; Fig. 6 is afront elevation of my improved window holder showing the same attachedto a window sash. Fig. 7 is a perspective View of the cam housing.

In its present embodiment my invention comprises a rectangular casing 1having one end thereof open as at 2 and the other end closed by the endpiece 3 which is formed integral with the bottom of said casing butwhich has its opposite ends cut therefrom, right angularly bent andsecured by rivets to the sides of said casing. Attaching flanges 4 areformed on the lower edges of said sides and provided with perforations 5for the reception of suitable fastening de vices 6.

To avoid the objectionable features connected with the ordinary sashfastener in which the window frame engaging member is pivotally mountedin the casing which latter when disposed on a loosely mounted windowsubject tc jars frequently causes said member to become jammed thusmaking it impossible for the operator to release the window when thesame has heel? locked in elevated position, I provide a cam housingwhich consists -of a plate having a width substantially equal to that ofthe casing and bent intermediate its ends to form the upper and lowercam attaching ears 7 and 8. This housing is slidably mounted within thecasing 1 and normally has the forward edges of the ears 7 and 8 incontact with the stops 9 formed on the sides of said casing adjacent theopen end thereof. Said housing is yieldably retained in this position bythe leaf spring 10 which has one end thereof secured to the inner sideof the end piece 3 and the opposite end engaged with the head of aT-shaped slot 11 formed in the curved portion of said housing.

Pivotally mounted between the ears 7 and S on the pivot at 12 is a cam13 which latter is disposed so as toV have the outer edge thereofprojecting beyond the forward edges of said ears and through the opening2 in said casing. For the manipulation of the cam 1.3 there is provideda bell crank 14: which is pivotally mounted in the casing 1 as at 15 andhas the outer portion of one arm thereof projecting through a.transversely extending slot 16 formed in the closed end of the casing 1said outwardly projecting portion being bent to a plane substantially atright angles to that of said arm to form a finger piece 17. The otherarm of said bell crank is pivotally connected to one end of the rod 18which passes through the shank of said T-shaped slot 11 and is pivotallyconnected at its opposite end to the lower edge of the cam 13.

From the foregoing, it will be seen that a. downward pressure on thefinger piece 17 will draw the rod 18 inwardly thus retracting the cam13. To normally retain the upper edge of the cam 13 in contact with theinwardly projecting tongues 19 which are cut from the ears 7 and S atdiametrically opposite points thereon and which are intended to limitthe outward movement of the cam 13, I employ a. helical spring 2O whichencircles the rod 18 and has one end secured to the outer portionthereof and the opposite end in engagement with shoulders 21 formed bythe shank of said T-shaped slot 11.

For convenience in operation I employ a radially projecting grippingmember 22 which is eXteriorly secured to one side of the casing 1adjacent the closed end thereof and adapted to co-act with said ingerpiece 17.

The operation of my improved Window lock is as follows Before raisingthe Windoiv the iinger piece 17 is depressed which compresses the springQ0 and retracts the cam 13. The Window is then raised to the desiredelevation after which the finger piece 21 is released, permitting theca-m 13 under the infiuece of the spring 2O to come into engagement withthe Window casing thus holding said Window in an elevated position.

From the foregoing description taken in connection with the accompanyingdrawings, the construction and operation of the invention Will bereadily understood Without requiring a more extended explanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to Without depart-ing from the principle orsacricing any of the advantages of the claimed invention.

Vhat I claim is:

1. In a Window holder of the character described, the combination With acasing provided with attaching means and having one end thereof open, ofstops adjacent said open end, a cam housing slidably mounted Within saidcasing, a cam pivotally mounted therein and having one edge projectingtherefrom and through the open end of said casing, means Within saidhousing to limit the outward movement of said cam, means adapted toretract said cam, means connected with said last mentioned means to holdsaid cam in projected position and a spring to normally retain saidhousing in yieldable engagement with said stop.

2. In a Window holder of thc character described, the combination with acasing provided with attaching means and having one end thereof open, ofstops adjacent said open end, a` cam housing slidably mounted withinsaid casing, a cam pivotally mounted therein and having one edgeprojecting therefrom and through the open end of said casing, apivotally mounted iinger press, a connect-ing member having one endsecured to the inner end of said finger press, the opposite end thereofbeing secured to said cam whereby the latter may be retracted, meansdisposed upon said connecting member and adapted to hold said cam inprojected position and a spring to normally retain said housing inyieldable engagement with said stops.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
